------------------------------------

             Summary: Remove AkkaUtils.ask to encourage explicit future handling
                 Key: FLINK-1508
                 URL: https://issues.apache.org/jira/browse/FLINK-1508
             Project: Flink
          Issue Type: Bug
            Reporter: Till Rohrmann


{{AkkaUtils.ask}} asks another actor and awaits its response. Since this constitutes a blocking call, it might be potentially harmful when used in an actor thread. In order to encourage developers to program asynchronously I propose to remove this helper function. That forces the developer to handle futures explicitly.
